Summation Current Transformers
A summation current transformer magnetically combines suitable input currents into an output representing their specified aggregate.

Product & engineering
Understand the product.
Input ratios, phase relationships and winding configuration determine the resulting measurement. Matched primary CTs and correct polarity are essential.
The connected meter and wiring contribute burden. Accuracy must be considered for the complete measurement chain and intended current range.
What turns activity into demand
Trace the complete current measurement chain before comparing units. Separate summation transformers from primary measuring CTs and residual-current sensing arrangements.
The commercial boundary
Separate summation transformers from primary measuring CTs and residual-current sensing arrangements.
